"Science creates e-snitch to get you to stop drinking"
Sometimes to kick a habit, all we need is a gentle prod. Or in this case, a subdermal electronic snitch. These chips totally narc on you when you decide to get drunk. Researchers at the University of California San Diego (UCSD) developed the tech, which is a biosensor of one cubic millimetre in size. So, how does it work? Well, when the person/subject drinks, an enzyme coating the sensor rockets a wireless electrical signal to a second party, such as a smartwatch, or an app, anything that remotely powers the sensor.
"This Implantable Chip Could Monitor Alcohol Intake"
People arrested for DUIs or other alcohol-related offenses are sometimes ordered to wear so-called SCRAM (secure continuous remote alcohol monitoring) bracelets. The device, usually worn on the ankle, can detect alcohol consumption through the skin. Patients in rehab programs often submit to alcohol monitoring as well, often through Breathalyzers or blood tests. But SCRAM bracelets are clunky and sometimes embarrassing, and tests require regular visits. A team of scientists from UC San Diego has come up with a potential alternative: a tiny implantable chip.

"Injectable chip measures alcohol consumption"
There may be a new -- if perhaps somewhat Big Brother-like -- method of monitoring the alcohol intake of people in substance abuse treatment programs. Led by Prof. Drew Hall, scientists at the University of California San Diego have developed an alcohol-sensing chip that can be implanted in the body. The chip is designed to be injected under the skin, where it will sit in the interstitial fluid that surrounds the cells. The chip uses very little power (which it draws from the watch's RF signals) and takes just three seconds to conduct one measurement.
"Trying to Quit Drinking? This Implant Will Snitch If You Fall off the Wagon"
Christmas parties. Dates. Football games. Cookouts. Wherever humans socialize, you can bet that the booze will follow. Its omnipresence, plus its addictive qualities, can make it really hard for people to stop drinking, even if they really want to. Now, researchers are working on a new alcohol-monitoring implant that could help people stay on the wagon. All they'll have to give up is some of their autonomy. Researchers at the University of California San Diego developed the implant, a biosensor about one cubic millimeter in size. It's easy to implant under a person's skin, no surgery requir
"A temporary tattoo may be able to track your alcohol levels"
A new monitoring device could help people discreetly measure their alcohol intake by transmitting alcohol levels to a connected cell phone. The tech, developed by engineers at the University of California San Diego, is a small wearable, comparable to a temporary tattoo, that sits directly on the skin. According to Science Daily, it works by stimulating perspiration, which the device can then use to measure the level of alcohol in the person's system.
